Universal Cleaner vs. Bathroom & Shower Cleaner: What’s the difference?Updated 6 hours ago

TL;DR: Universal Cleaner is a spray-and-wipe, no-rinse formula for everyday cleaning across 20+ surfaces including the bathroom. Bathroom & Shower Cleaner is an enzyme-powered foam designed to break down soap scum, body oils, and bathroom build-up. It needs dwell time and rinsing. They're partners, not replacements. UC for quick weekly clean, BSC for the deeper monthly scrub.

What's the difference between them?

Universal Cleaner is built for breadth: a two-ingredient alkaline formula (potassium hydroxide + water) that handles grease, grime, and light soiling across 20+ surface types. Spray, wipe, no rinse needed. Bathroom & Shower Cleaner is built for depth: an 11-ingredient enzyme-powered foam (including lipase, surfactants, and builders) that clings to vertical surfaces and breaks down soap scum, body oils, and hard-water build-up. Needs dwell time and a water rinse.

Which one should I use in the bathroom?

Use both, at different times. Universal Cleaner is great for quick bathroom touch-ups: wiping basins, benchtops, mirrors, and toilet exteriors without rinsing. Bathroom & Shower Cleaner is the right tool for the shower screen, tiles, grout, bathtub, and anywhere soap scum or body oils build up. The foam clings to vertical surfaces, the enzymes work on organic grime, and the rinse carries everything away clean. Many people use both: UC for midweek touch-ups, BSC for the weekly deep clean.
